This sounds easy, and it is. And, in the past I’ve cut up pounds and pounds of strawberries. I’ve sliced them, diced them, and chopped them. And usually they leave red berry stains on my cutting board, on my counter and on my hands.
Well, no more.
Here is an easy way to cut up strawberries that is also fast:

Using a paring knife, cut the stem and core out. The core is sightly bitter and it’s a good idea to get rid of it. You don’t have to go very deep, about 1/4” to 3/8” should do it.

Place the cored strawberry on the cutting board sitting on its fat end.

Do all the strawberries this way (see photo above)

Next, take each strawberry and cut twice vertically from the top end to the bottom cutting the berry into quarters (see photo above).

Grab the whole strawberry near the base and throw it into a bowl.

Once you get the hang of this technique, it goes really fast.
Because of the way they are cut, the berries stick together and you do not have to handle the cut edges of the berries so everything stays cleaner. Especially your hands.
Now, go cut up some strawberries and make some great strawberry short cake!
